I INKING MECHANISM.

Application filed January This invention relates to certain improvements in inking mechanism for printing machines.

In certain types of inking mechanism, par- 5 ticularl that shown in United States Letters Patent 10. 1,214,856, dated February 6, 1917 and No. 1,311,198, dated July 29, 1919 to B. C. White, the ink is delivered or supplied through a series of independentconduits a separate conduit being provided for each column orother desired section of the form. In this type of inking mechanism the ink is delivered under-pressureto the conduits in regulated uantity by a plurality of pressure devices suc as pumps, one pump bein provided for eachconduit, and-the conduits deliver to separate nozzles which are arranged to extend across the mechanism adjacent the.

member to which the ink is to be delivered, these nozzles or openings being provided in a frame or frame member which, inthis type of mechanism, is termed the ink rail. The nozzles or openings are provided one for each column or section of the form. Under some circumstances it becomes desirable to produce'products having different numbers of columns or other form sections, and where it is desired to produce a product havingja difierent number of columns or form sections from that for which the distributing nozzles or openings are designed, it is necessary to dismantle J the ink rail and conduits and substitute a rail having a difl'erent arrangement or number of distributing openings. This operation is slow and takes up an amount of time which, in press operation, is undesirable because of the justments.

It is the especial object of the present inven tion to produce a construction in which the ink distributing openings or nozzles can be readily and quickly varied ,to accommodate the mechanism to 7 numbers of columns or form sections. It is a further object of the invention to produce sucha construction which is simple, easily accessible and inwhich the parts can be quicklyand accurately adjusted.

s print- (not shown) in any suitable or illustrated as unnecessary for an understanding of the invention. v The inking mechanism includes'a frame or the machine, Ink is delivered tothis rail through a. plurality of conduits 3, one of these an ink rail 2.which extends across conduits being provided for each column or for desired sections of the form or forms on the form member of the In the particular construction shown for; illust-rative purposes, there are thirty-two of printing couple; 9

these conduitsfor supplying ink to four-page I wide plates, each page being eight columns wide. Ink is delivered to these conduits under pressureby means of a pluralit of pressure devices, not shown, such as t e pumps of the White patents above referred to, these pumps being located in a fountain or reservoir indicated generally by the numeral 4.

Ink is delivered from the conduits to ink delivery openings or nozzles 5, one of these nozzles being rovided for each conduit and being formed 1n the ink rail before referred which is so constructed and arranged that it may be readily and quickly removed and replaced with another distributing member having a different number of ink distributing openings or nozzles and from which the ink is delivered to the distributor.

While the specific construction and arrangement of this member may be widely varied, in the particular construction illustrated this distributing member is in the form of a plate or bar, and preferably this bar is centrally divided, as indicated at 6 in Figure 2, the two parts of this bar being marked 7 and 8. This bar is secured in position on the rail by screws 9 and is held in position in any suitable way.

In the particular construction shown, .the top of the rail 2 is undercut, as indicated at 10 in Figure 1, and the bottom of the bar is formed with beveled portions 11 cooperating with the undercut portion 10 of the rail so that the bar is securely held in position but may be readily taken out by simply removing the screws 9 and sliding the two parts of the bar endwise of the rail.

This bar is provided with the required number of distributing nozzles or openings, thirty-two being shown in the present 1nstance corresponding to the thirty-two columns or sections of a four-page wide paper having eight columns to the pa e, these nozzles bein marked 12 and deliverlng to the ink distributing member 1 before referred to. Communication to the nozzles 12 in the bar and the nozzles 5 in the rail is provided by means of ports 13 formed in a central web 14 of the bar, one of these ports being provided for each of the nozzles 12.

In the best constructions the discharge nozzle or openings of the ink distributing member are formed so as to break up the stream of ink flowing therefrom so as to afford a smooth, even distribution of the ink from each of the nozzles. In the particular construction illustrated (see Figure 3) the ink bar 7-8 is formed with partitions 15 which separate the nozzles from each other, and between the partitions are provided projections 16 which form channels 17 through which the ink flows to the distributor 1.

Cooperating with the ink distributing bar is a cap or cover plate 18, 'this cover plate,

when in closed position, resti onithe partitions 15 and the profections -1 as shown in Figure 1, so that the llllk is properly directed through the nozzles. This cover plate 18 is secured to the rail 2 so that it may be moved to afford access to the nozzles for cleaning or other purposes and, as shown, itis hinged to the rail by a hinge 19 and is held in closed position by springs 20, which bear against the projections21.

While the ink distributing member is shown as formed in a bar which is separate from the rail and the cover, it will be understood that under some circumstances, if desired, the ink distributing member having the distributing ports 12 might be formed in the cover 18 and the invention is, therefore, not to be restricted to thisseparate bar.

The ink rail and the parts associated therewith may be supported in any suitable side frames 22, and the conduits 3 may be conveniently supported in a recess 23 formed in the rail.

In use, if it is desired to change the ink distribution for a form having seven columns, for instance, instead of one having eight, the parts of the removable ink distributing member are removed from the machine and a member having a different number of discharge openings or nozzles substituted therefor, which, as. will be understood from the foregoing, can be readily and quickly accom lished.

While t e invention has been shownand described in its preferred form, it willbe understood that the removable. ink distributing member may vary from the specific construction and arrangement of that shown, and the invention is therefore not to be restricted to the construction, arrangement and position of the ink distributing member shown and described, this latter having been selected as embodying the invention in a preferred form.
